Big fan of Abe's videos. I also feel attacked on this one in particular as I'm guilty of "DO ALL THE THINGS TO FIX" approach.
4/7 of the acros I bought from him have STN'd, I assume because of my lack of tank maturity and possibly nutrient/param control. I'm taking a slow/steady approach now and I'm probably ~1-2 months in to the "just take a step back and see what happens" phase he talks about.
